The pre-stage of gastric cancer usually also includes pernicious anemia

Cancer is not scary, what is scary is that you don't know it has occurred after it occurs. Do you know the pre-stage of gastric cancer? Many people don't know, so they often go to the hospital for examination in the late stage. Let's follow our experts to look at the specific manifestations of the pre-stage of gastric cancer .

1. Pernicious anemia is one of the pre-conditions of gastric cancer: 10% of patients with pernicious anemia develop gastric cancer, and the incidence of gastric cancer is 5 to 10 times that of the normal population.

2. Remnant stomach: Cancer that occurs in the residual stomach after surgery for benign gastric lesions is called residual stomach cancer. The incidence rate increases significantly after surgery, especially 10 years after surgery, which is also the early stage of gastric cancer.

3. Chronic atrophic gastritis: Chronic atrophic gastritis is significantly positively correlated with the incidence of gastric cancer, so it is also one of the pre-cancerous conditions of gastric cancer.

4. Benign gastric ulcer: This is also a pre-stage of gastric cancer. Gastric ulcer itself is not a pre-stage of gastric cancer, but the mucosa at the edge of the ulcer is prone to intestinal metaplasia and malignant transformation.

5. Gastric polyps: Although adenomatous or villous polyps account for a small proportion of gastric polyps, their canceration rate is 15% to 40%. Those with a diameter greater than 2 cm have a higher canceration rate. Hyperplastic polyps are more common, but their canceration rate is only 1%.

The above is the specific manifestations of the pre-stage of gastric cancer introduced by experts. I believe everyone has already understood it. Experts remind everyone that some diseases have no symptoms, so regular physical examinations are the best way to detect hidden diseases in time and eliminate them as soon as possible.
